Sled is dialled in hinge member and is provided with shoulder hole B and the screw hole passing for hold-down bars, and it is arranged on hold-down bars by the shoulder hole B on it;
The hole D that pedicle of vertebral arch sled group screw rod is dialled on hinge member by sled is arranged on sled group hinge member, and vertical with tranverse connecting rod with hold-down bars;
The bottom of pedicle of vertebral arch lock nut is cancellous threads section, and middle part is locking screw thread section, and top is outer-hexagonal;
Described junction button, locking hinge parts and sled are dialled on hinge member screw are housed respectively.
The further technical scheme of the present invention is: locking hinge parts are positioned at the outside of two hold-down bars, and sled is dialled the inner side that hinge member is positioned at two hold-down bars.
The present invention further technical scheme is: the part in the C inwall of described hole is provided with female thread, and the part in locking screw thread section is plane.
The present invention further technical scheme is: the longitudinal section of locking hinge parts is shaped as rectangle and cuts away the pentagon at an angle below, the lower end of locking hinge parts be one with the wedge angle on inclined-plane; The longitudinal section that sled is dialled hinge member is shaped as rectangle and cuts away the pentagon at an angle below, sled dial the lower end of hinge member be one with the wedge angle on inclined-plane.
The present invention is owing to adopting as above design, the wound that has overcome present conventional therapy Therapeutic Method existence is long, hemorrhage many, easily infect, affect patient's the weak points such as external beauty treatment, compared with prior art, have applied widely, easy and simple to handle, in use Stability Analysis of Structures is reliable, has the stronger advantages such as anti-rotate effect.
